RESUMO
PURPOSE: Resveratrol has anti-infective, anti-inflammatory and antioxidant activities. The purpose of this study was to determine the effect of resveratrol in a rat experimental model of allergic rhinitis (AR). METHODS: Wistar albino rats were divided into three groups: control (n=7), AR with no treatment (AR+NoTr, n=7) and AR with resveratrol treatment (AR+Res, n=7). For AR+Res, AR was induced and resveratrol given on days 21-28. On day 28, the total blood IgE levels were measured. Allergic symptoms (sneezing, nose-rubbing, eye lacrimation and nasal congestion) were scored on a 0-3 point scale, and histopathological changes in the nasal mucosa were evaluated. RESULTS: Allergic symptom score of AR+NoTr was higher than the other two groups and the score of AR+Res was higher than the control group. Histopathologically, neither ciliary loss nor chondrocyte hypertrophy differed among the three groups; however, vascular congestion, inflammatory and plasma cell numbers, eosinophil and mast cell infiltration and goblet cell numbers were higher and mast cell infiltration was more prominent in AR+NoTr than in AR+Res and control. AR+Res and control did not differ significantly in any histological parameter. In AR+NoTr, nasal mucosa exhibited ciliary loss, squamous epithelial metaplasia, inflammatory cell infiltration, vascular congestion of the lamina propria and goblet cell epithelial metaplasia. In AR+Res, goblet cell metaplasia was focal or absent and infiltration of the lamina propria by inflammatory cells, eosinophils, and plasma cells was reduced relative to AR+NoTr. CONCLUSION: Allergic symptoms and tissue reactions were reduced by resveratrol treatment in rats with experimentally-induced AR.

Allergen immunotherapy is a form of long-term treatment that decreases symptoms for many people with allergic rhinitis, allergic asthma, conjunctivitis (eye allergy) or stinging insect allergy. In this review, we presented the important topics in immunotherapy. The important aspects of immunotherapy are considered to be "Immunological responses to immunotherapy"; "The principal types of immunotherapy"; "Effectiveness"; "Indications"; "Contraindications"; "Allergen immunotherapy in children"; "Safety"; and "Anaphylactic reactions after immunotherapy". The principal types of immunotherapy are subcutaneous immunotherapy (SCIT) and sublingual immunotherapy. Both of them can be used in indicated cases. When using SCIT, physicians must be more careful because of reported rare fatal cases. The risks and benefits of continuing allergen immunotherapy in patients who have experienced severe systemic reactions should be carefully considered.

Leukotrienes (LTs) are a family of inflammatory mediators including LTA4, LTB4, LTC4, LTD4, and LTE4. By competitive binding to the cysteinyl LT1 (CysLT1) receptor, LT receptor antagonist drugs, such as montelukast, zafirlukast, and pranlukast, block the effects of CysLTs, improving the symptoms of some chronic respiratory diseases, particularly bronchial asthma and allergic rhinitis. We reviewed the efficacy of antileukotrienes in upper airway inflammatory diseases. An update on the use of antileukotrienes in upper airway diseases in children and adults is presented with a detailed literature survey. Data on LTs, antileukotrienes, and antileukotrienes in chronic rhinosinusitis and nasal polyps, asthma, and allergic rhinitis are presented. Antileukotriene drugs are classified into two groups: CysLT receptor antagonists (zafirlukast, pranlukast, and montelukast) and LT synthesis inhibitors (5-lipoxygenase inhibitors such as zileuton, ZD2138, Bay X 1005, and MK-0591). CysLTs have important proinflammatory and profibrotic effects that contribute to the extensive hyperplastic rhinosinusitis and nasal polyposis (NP) that characterise these disorders. Patients who receive zafirlukast or zileuton tend to show objective improvements in, or at least stabilisation of, NP. Montelukast treatment may lead to clinical subjective improvement in NP. Montelukast treatment after sinus surgery can lead to a significant reduction in eosinophilic cationic protein levels in serum, with a beneficial effect on nasal and pulmonary symptoms and less impact in NP. Combined inhaled corticosteroids and long-acting ß-agonists treatments are most effective for preventing exacerbations among paediatric asthma patients. Treatments with medium- or high-dose inhaled corticosteroids, combined inhaled corticosteroids and LT receptor antagonists, and low-dose inhaled corticosteroids have been reported to be equally effective. Antileukotrienes have also been reported to be effective for allergic rhinitis.

In the present study, we investigated the outcomes of sublingual immunotherapy (SLIT) in house dust mite-induced allergic rhinitis (HDM-AR) patients. In this prospective, multicentric study, 186 patients with AR who had positive skin prick test results for HDMs were included. The patients were administered SLIT using Staloral 300 for 1 year. Evaluation of the patients regarding symptom scores, clinical findings and Rhinitis Quality of Life Questionnaire (RQLQ) scores was performed at baseline, and then at 6 and 12 months of therapy. Our results showed that, for all of the evaluated items (symptom scores, clinical findings and RQLQ scores), 12-month values were significantly lower than those at 6 months and baseline. Similarly, 6-month values were significantly lower than those at baseline. There were no complications in any of our patients. SLIT for HDM-AR is a treatment modality that can be used safely. We obtained better results than expected, and the treatment showed a positive psychological effect; the patients believed that SLIT was the final step of treatment and, which made them feel better.

OBJECT: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. METHODS: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. RESULTS: A detailed guideline about all aspects of allergic rhinitis was created. CONCLUSION: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.
RESUMO
OBJECTIVES: We evaluated three-year clinical and laboratory results of specific immunotherapy (SIT) for allergenic house dust mite species, Dermatophagoides pteronyssinus and D. farinae. PATIENTS AND METHODS: The study included 26 patients (6 males, 20 females; mean age 28 years; range 17-56 years) who had allergic rhinitis and were found to be sensitive to D. pteronyssinus and D. farinae. Due to unresponsiveness to other treatment modalities, the patients received subcutaneous SIT for three years. Symptoms (nasal stuffiness, rhinorrhea, itching, sneezing, headache, eye symptoms, and smelling) were graded before and at the end of SIT, and blood eosinophilia, total IgE and specific IgE levels were determined. RESULTS: At the end of three years, the number of patients that showed strong positivity to D. pteronyssinus and D. farinae decreased from 26 (100%) to 3 (11.5%) (p=0.0001) and from 18 (69.3%) to 4 (15.4%) (p<0.005), respectively. There were significant decreases in blood eosinophilia, total IgE and specific IgE levels, and in the severity of all symptoms related to the nose, head, and eye. CONCLUSION: Specific immunotherapy reduces symptoms in patients with allergic rhinitis. It is an effective treatment method for allergic rhinitis if performed by trained physicians in carefully selected patients.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most frequent peripheral vestibular disorder and is particularly seen among older patients suffering from vertigo. The brief vertigo attacks in and imbalance symptoms of BPPV are caused by freely floating otoconia within the semicircular canals. The aim of this prospective study was to evaluate the role of oxidative stress, using native thiol/disulfide (SH/SS) homeostasis as a novel indicator, in the etiology of BPPV. MATERIALS AND METHODS: The 62 participants in the study included 31 patients with BPPV and, as the control group, 31 healthy individuals without any cochleovestibular disorders. RESULTS: Patients with BPPV initially had significantly lower native SH levels and significantly lower SH/total thiol (TT) ratios, as well as significantly higher SS/SH and SS/TT ratios, than the healthy controls. After successful treatment of their vertigo, which was confirmed based on the results obtained from the second blood sample, patients with BPPV still had lower SH levels and SH/TT ratios and significantly higher SS/SH and SS/TT ratios than the healthy controls. CONCLUSION: Our results suggest a role of oxidative stress in the development of BPPV, through both calcium metabolism and the direct toxic effects of free oxygen radicals, including the triggering of apoptosis.

OBJECTIVE: The value of vestibular rehabilitation in patients with bilateral vestibular dysfunction was investigated. MATERIALS AND METHODS: This study assessed 17 patients (9 males, 8 females) with bilateral vestibular dysfunction. Vestibular rehabilitation continued for 1.5 months. Videonystagmography tests (including oculomotor testing, positional testing, and caloric tests), vestibular evoked myogenic potential (VEMP) testing, and computerized dynamic posturography were performed during the pre-, mid-, and post-treatment periods. The patients underwent cranial and internal acoustic canal MRI. Consultant physicians from the neurology and physical medicine and rehabilitation departments reviewed all patients. RESULTS: The post-treatment anteroposterior somatosensorial (APSO), anteroposterior global (APGLO), mediolateral visual (MLVI), and mediolateral global values and anteroposterior and mediolateral trials and conditions were significantly higher than those measured in the pre-treatment period. Similarly, mid-treatment values of the APSO, APGLO, and the anteroposterior sensory organization test (SOT) 2 were significantly higher than those measured in the pre-treatment period. CONCLUSION: Vestibular rehabilitation was effective in patients with bilateral vestibular dysfunction. As the vestibular rehabilitation duration increased, so did the efficacy of the treatment.

BACKGROUND: Although the definition of anaphylaxis for clinical use may vary by professional health care organizations and individuals, the definition consistently includes the concepts of a serious, generalized or systemic, allergic or hypersensitivity reaction that can be life-threatening or even fatal. METHODS: In this review, we presented the important topics in the treatment of anaphylaxis in the office setting. This review will discuss triggers and risk factors, clinical diagnosis, and management of anaphylaxis in the office setting. RESULTS: Anaphylaxis in the office setting is a medical emergency. It, therefore, is important to prepare for it, to have a posted, written anaphylaxis emergency protocol, and to rehearse the plan regularly. In this review, we presented the important steps in managing anaphylaxis in the office. Treatment of anaphylaxis should start with epinephrine administered intramuscularly at the first sign of anaphylaxis. Oxygen and intravenous fluids may be needed for moderate-to-severe anaphylaxis or anaphylaxis that is quickly developing or if the patient is unresponsive to the first injection of epinephrine. Antihistamine therapy is considered adjunctive to epinephrine, which mainly relieves itching and urticaria. Corticosteroids, with an onset of action of 4-6 hours, have no immediate effect on anaphylaxis. CONCLUSION: To prevent near-fatal and fatal reactions from anaphylaxis, the patient, the family, and the physician must remember to follow the necessary steps when treating anaphylaxis. In anaphylaxis, there is no absolute contraindication for epinephrine.

OBJECTIVES: Although most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor. METHODS: Forty children with adenoid hypertrophy and 40 healthy subjects aged 5-15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3)2S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan). RESULTS: The mean CH3SH and (CH3)2S levels were significantly different (p < 0.05) between the adenoid hypertrophy group and the controls. The H2S, CH3SH, and (CH3)2S levels in the third postoperative month were significantly lower (p < 0.05) than those in the preoperative period, and there was no significant difference postoperatively between the patients with adenoid hypertrophy and controls. There was a positive correlation between age and VSC levels, and CH3SH levels were significantly higher in patients with ventilation tube insertion, rather than just adenoidectomy. CONCLUSIONS: There was a statistically significant association between halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.

BACKGROUND: Some alternative products instead of immunotherapy are used in patients with allergic rhinitis (AR). METHODS: In this paper, alternative products to treat allergic rhinitis and alternative routes for allergy immunotherapy are reviewed. RESULTS: Alternative products and methods used instead of immunotherapy are tea therapy, acupuncture, Nigella sativa, cinnamon bark, Spanish needle, acerola, capsaicin (Capsicum annum), allergen-absorbing ointment, and cellulose powder. N. sativa has been used in AR treatment due to its anti-inflammatory effects. N. sativa oil also inhibits the cyclooxygenase and 5-lipoxygenase pathways of arachidonic acid metabolism. The beneficial effects of N. sativa seed supplementation on the symptoms of AR may be due to its antihistaminic properties. To improve the efficacy of immunotherapy, some measures are taken regarding known immunotherapy applications and alternative routes of intralymphatic immunotherapy and epicutaneous immunotherapy are used. CONCLUSION: There are alternative routes and products to improve the efficacy of immunotherapy.

BACKGROUND: Allergen immunotherapy (AIT) leads to the production of antiallergen immunoglobulin (IgG) or "blocking antibody" in the serum and an increase in antiallergen IgG and IgA in nasal secretions. There is also a decrease in the usual rise in antiallergen IgE that occurs after the pollen season. METHODS: In this paper, mechanisms of action of allergen immunotherapy is reviewed. RESULTS: Regulatory T (Treg) cells and their cytokines, primarily interleukin (IL) 10 and transforming growth factor beta, suppress T-helper type 2 immune responses and control allergic diseases in many ways. AIT induces a shift in the proportion of IL-4-secreting T-helper type 2 cells in favor of IL-10-secreting inducible Treg cells specific for the same allergenic epitope that increases in number and function. Different types of inducible Treg control several facets of allergic inflammation. There are two main types of immunotherapy: subcutaneous immunotherapy and sublingual immunotherapy. Subcutaneous immunotherapy is efficacious and is indicated for the reduction of seasonal symptoms. Sublingual immunotherapy involves the regular self-administration and retention of allergen extract under the tongue for 1-2 minutes before the extract is swallowed. The allergens cross the mucosa in 15-30 minutes and are then captured by tolerogenic dendritic cells and processed as small peptides. Next, via the lymphatic system, a systemic immune response is created to produce an early decrease in mast cell and basophil degranulation. CONCLUSION: AIT is indicated for the treatment of moderate-to-severe intermittent or persistent symptoms of allergic rhinitis. AIT can be administered to those >5 years of age and has been shown to be safe in children as young as 3 years of age. In this article, AIT and other types of immunotherapies were discussed as well as the indications for immunotherapy.

OBJECTIVES: Physicians have long had concerns about the potential harmful effects of pediatric septoplasties on the nasoseptal growth process because septal cartilage is important for the growth and development of the face. METHODS: In this review article, pediatric septoplasty and its indications are discussed, together with a literature survey. In addition, overviews of development of the nasal skeleton from neonate to adult, nasal growth, and cartilaginous septum are presented. Important issues and comments on pediatric septoplasties are provided. RESULTS: During septoplasty procedures, elevation of the mucoperichondrium unilaterally or bilaterally does not negatively affect growth of the face. Stabilization of the septum may be easier when mucosal elevation is performed unilaterally. The nasal floor mucosa should not be elevated so to avoid damage to the incisive nerves. Corrections and limited excisions may be done from the cartilaginous septum. Separation of the septal cartilage from the perpendicular plate, especially at the dorsal part, should not be performed because this area is important for the length and height of the nasal septum and nasal dorsum. Incisions or excisions should not be performed through the growing and supporting zones, especially at the sphenoethmoid dorsal zone. CONCLUSION: If there are severe breathing problems related to the septal deviation, septoplasty should be performed. In the majority of cases, septal surgery may be conducted in 6-year-old children. However, if necessary, septal surgery may be performed in younger children and even at birth.

OBJECTIVES: The surgical anatomy of the nasal tip is determined by intrinsic factors, such as the nasal tip volume, shape, definition, and symmetry. These factors are intimately related to the morphology of the lower lateral cartilages. Tip sutures reduce the need for grafts and allow the surgeon to manipulate the tip with a high degree of precision and better long-term clinical outcomes. In this review, we evaluated common nasal tip suture techniques to clarify the similarities and differences among them. METHODS: The following nasal tip suture techniques were investigated: medial crural fixation suture, middle crura suture, transdomal (dome creating, dome binding, domal definition) suture, interdomal suture, lateral crural mattress suture, columella septal suture, intercrural suture, tip rotation suture, craniocaudal transdomal suture, lateral crural spanning suture, suspension suture, tongue-in-groove technique, and lateral crural steal. RESULTS: Tip sutures increase tip projection, narrow the tip, provide stabilization, and provide tip rotation. The sutures may be used separately or together. CONCLUSION: Nasal tip sutures have long been used as noninvasive suture techniques. Each suture technique has unique benefits, and various key points must be considered when using these techniques.
